Application of the Magnetic Field to High Temperature Optical in Situ Observation Technique

A magnetic-field applied to high temperature optical in situ observation (M in situ observation) technique was established in the authors' laboratory. An electromagnet was used as amagnetic field generator. This magnet was designed to supply up to 0.14T transversely to thecenter of the heater.By using M in situ observation technique, the relative extent of boundary layer can be reducedand the buoyancy driven convection can also be damped. The effect of the magnetic-field uponoxide crystal growth was verified tentatively.
